FEEDING ncnaivrsm non CONTAINERS.

7 Application filed June 29, 1926. Serial No. 119,460.

This invention relates to improvements in feeding mechanism for containers and the like, and the objects of the invention are to provide a simple and effective means to extrude or feed material from a container and simple and effective means to apply power to the feeding means.

Further objects of the invention are to provide an improved form of releasable connection for converting rotary into reciprocating motion. v

The invention comprises the improved construction and arrangement of parts hereinafter described in detail in the accompanying specification and drawings.

In the drawings, in which like characters of reference indicate corresponding parts in each figure: t

Figure l is a sectional elevation of an embodiment of the invention;

Figure 2 is a sectional elevation of a modified form of the invention;

Figure 3 is a sectional elevation of a further modified form of the invention;

Figure 4 is a sectional elevation of another alternative forincf the invention;

Figure 5 is a sectional detail of the reciprocatory shaft or rod used to transmit power and form the releasable engagement.

Referring to the drawings, A indicates a suitable container which may be made of any convenient material such as metal, celluloid, glass or the lilre. The material from which the container is formed and its shape may be chosen to suit the material to be contained therein. I have shown a cylindrical form of container having a suit-able top 10 with an extruding orifice or nozzle 11. B indicates a follower or extruding member mounted on the container and contacting with the walls thereof preferably of a light resilient material such as cork and C indicates a rotary or reciprocatory shaft or rod extending transversely across the container and journalled in the walls thereof. The reciprocation of this shaft or rod is designed to effectmovement of the extruding member B through operation of a connecting and power-transmitting member D. The connecting member D is conveniently 1n the form of a soft metal wire having one end extending through an opening 12 in the member B and connected to a plate 13 on the underside thereof. The opposite end of the member D is formed with a relatively tightly wound spiral. spring 14: which surrounds the shaft C. the tension of the spring and closeness of the winding being such that when the shaft (1 is turned in one direction it will tighten the spring and cause it to grip the shaft to wind up a further portion of the wire D,

. while movement in the reverse direction will release the spring 1% from the shaft C. In order to more effectually ensure that this releasaljile clutch action will take place the shaft or rod C is preferably formed with a friction surface 15 which may be formed by coating either the wire or the shaft with soft metal such as lead. As shown, the shaft itself is coated with the metal.

The shaft C is designed to be reciprocated by suitable means. In Figure 1 a bail E is attached to the extremity of the shaft, while in Figure 2 a lever 16 is attached to one end of the shaft. This bail, which may be formed from spring wireymay conveniently carry a cover 17 for the orifice or nozzle 11 whereby in using the device, one movement of the bail l1] will uncover theoritice and actual e the entrudingmember to extrude whatever i'naterial is in the container, such material being conveniently in the form of a paste or cream. In order to prevent tilting of the extruding member B when the pressure is exerted by the connecting member D the portion of the wire extending through the member B is preferably rigid or, alternatively, the wire is connected to a rigid pin 18 extending through the member B.

In the alternative form of the invention shown in Figure 3, the reciprocable shaft member C extends through the end of the container in an axial direction, while the connecting member D extends over a cross pin 19 before extending around the member C. The discharge orifice 20 is formed at one side of the container.

in the alternative form of the invention sociated therewith.

shaft or rod and power-applying means as- The device is particularly adaptable for use in inexpensive forms of containers which are only used once. It will be observed that the soft metal wire, constituting the member D or D, functions in part as a. clutch and its resiliency should be such that it would be capable of being wound about the shaft and also acting as a reliable clutch in the manner stated.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope ofthe claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. In combination, a receptacle shaft member, a spring member extending spirally around the same and adapted to form a releasable connection therewith, and means forming a soft friction surface between the shaft and thespring member.

2. In combination, a reciprocable shaft member, a spring member extending spirally around the same and adapted to form a. re-

leasable connection therewith, and a soft metal connection between the shaft and the spring: member.

, 3. In combination, a container, a reciprocable shaft transversely mounted therein. a follower in the container, a longitudinally extending wire connected to the follower having an integral spring end wound about the shaft adapted to form a releasable connection therewith and a soft metal coating about the shaft, adapted to form a connection with the spring end.

4:. In combination, a reciprocable member having a cylindrical surface, aspring memher extending spirally around the cylindrical surface adapted to form a releasable connection therewith, and soft friction-producin: means between the spring and the shaft.

In combination, a reciprocablc member having a cylindrical surface, a spring member extending spirally around the cylindrical surface adapted to form a releasable con nection therewith, and a soft metal connection between the spring and the shaft.

' 6. In combination, a container having an orifice, a pivoted bail mounted on the container, a cap on the bail, a follower member, a wire connected to the follower member having releasable connection with the bail.

7. In combination, a container havingan orifice, a pivoted bail mountcclon the container, a shaft connected thereto, a cap on the bail, afollower member, a wire connected to the follower member having rcleasable connection with the shaft formed by spirally winding a portion of thewirc about the shaft. i

8. In combination, a containen having an orifice, a cap for the orifice, an extruding member in the container and means operatecl by removal of the cap for actuating the extruding member.

In witness whereof I have hereunto set my hand.

WILLIAM HENRY GREGORY GEAKE.
